Abstract
Ceramic SiCO fibers are formed by spinning a mixture of a substantially linear polysiloxane fluid having unsaturated hydrocarbon substituents and a photoinitiator into a fiber, exposing the fiber to radiation, and heating the fiber in an inert environment to a temperature above about 800.degree. C.
